The Pierce Quantitative Colorimetric Peptide Assay is designed to provide a sensitive, mix and read microplate assay for determining peptide concentrations. This assay leverages a modified Bicinchoninic Acid (BCA) method, a well-established technique in protein and peptide quantification. The core principle involves the reduction of copper(II) ions to copper(I) ions by peptides in an alkaline medium. This reduction is facilitated by the peptide bonds and certain amino acid side chains (like cysteine, cystine, tyrosine, and tryptophan).Pierce BCA Protein Assay Kit (MAN0011430 Rev. A) The resulting copper(I) ions then form a stable, purple-colored complex with bicinchoninic acid. The intensity of this color, measured spectrophotometrically at an absorbance of 480 nm on instruments like the Synergy HT, is directly proportional to the peptide concentration in the sample.Pierce™ Quantitative Peptide Assays & Standards
